This news item from a few weeks ago revealed that when users created a “public link” of their Claude chat history, that chat history ended up in Google’s search queries.
Aren’t these urls supposed to be more or less undiscoverable by virtue of the long string of random characters that they contain?
How did Google discover those urls?
Did these people publish the urls somewhere publically themselves?
Or did Google “fish” them out of their gmail inbox or something like that?


Anthropic fucked up, Claude is not a person.
Correct, that seems to be the case.
Kind of. The user fuck up would be not realizing that Anthropic had no protections from search engines, and that by clicking “share” they were creating publicly accessible links.
Anthropic seems to have updated the domain those links are generated on so that crawlers do not index public chats, yes.
I am also curious. I looked it up. https://developers.google.com/search/docs/fundamentals/how-search-works
If I had to guess based on this, Google had probably indexed the domain Claude or its frontend run on and automatically scooped up the public chats as they became available.
It is also possible that any Claude chat shared will still be accessible to web crawlers, if they just ignore the flags telling them not to scrape, crawl, access, index, etc.
Thank you this was very helpful.
